I'm trying to match a string using regex. The format is like this:

[AN][AN][N][N][N][AN][AN] where AN is alphanumeric upper case character and N is a numeric character
What I'm doing is to save the string into a variable and then check it against a define pattern:

myPattern.matches("([A-Z0-9]{2})([0-9]{3})([A-Z0-9]{2})");

Apparently this is not the way to do it as it matches strings like "AZS..34"

I'm not certain, but I would try removing the parentheses, since those are capturing groups and are not needed because you aren't using back references.

Never done Regular Expressions in Java, though, so unsure. Usually use Perl or C for this.

Many thanks Greg. I should learn to read the API :D
To solve the problem:

Pattern.matches("([A-Z0-9]{5}+[0-9]{6})", "myPattern")

it works smoothly like this.

Thanks again
